Return to Play with Healthy HamstringsHamstrings

 

High incidence rate, slow healing, persistent symptoms, and a historically high rate of recurrence have made hamstring injuries a challenge for both athletes and the clinical team responsible for their recovery.

There is mounting evidence that the risk of re-injury can be minimized by using rehabilitation strategies that incorporate neuromuscular control exercises and eccentric strength training, combined with objective measures to assess recovery and readiness to return to sport.1

System 4 Supports Hamstring Protocols

Regardless of whether you have an existing process for protecting and strengthening hamstrings, the objective test protocols offered with the Biodex™ System 4 will provide valuable, isolated muscle-performance data. Test results, combined with established targeted outcomes, can be used for pre-emptive injury screening, managing rehabilitation and determining readiness for returning to play.

NEW Return-to-Play Reports

Biodex introduces the first Return-to-Play report for hamstring injury, now available with System 4 Advantage BX™ software:

 

Upgrade path available for existing System 4 and System 3 (rev. 2) dynamometers.


Protocol #1:

Lengthened State – Multiple Angle Comparison Test

Examines isometric bilateral flexion peak torque symmetry where the limb position puts the hamstring in a lengthened (stretched) state. Passive stretch is the inherent force (or torque) produced by the hamstring in the lengthened state. When deficits are within 10%, predisposition to reinjury is significantly reduced.

NOTE: This Protocol requires 830-550 Hamstring Attachment. Use of any attachment other than the 830-550, is outside proper and intended use.

With this report, Physicians can understand report at a glance with clear pass/fail results.

Protocol #2:

Mixed H/Q Ratio Test

Uses a ratio of eccentric and concentric flexion peak torque where, if the ratio exceeds 1.4, hamstring injury is greatly diminished.
Now available with Advantage BX™ 5.3.

NOTE: This Protocol utilizes the standard Biodex Knee Attachment.
